3,632 impression in 21days with 56 click and earn 4.55$ give me advise what wrong with this or i am not worry for this
your CTR is about 1.5%, consider ok but still can be improved. CPC is about $0.10, this is quite low, try to add some high pay keyword. The major factor shall be traffic, your traffic not good enough
CTR seems to be low and can be improved. Higher traffic means higher income and try to find ways and means of getting targeted traffic.
